  • Patent number: 9011766
    Abstract: A method for increasing the shelf life of donor blood contemplates the following steps. In the first step blood is transferred to a sterile container and mixed with an anticoagulant as indicated in step 20. The anticoagulant and donor blood are centrifuged in step 22 at about 4,000 rpm for about 15 minutes. After centrifuging the red blood cells are separated and placed in a sterile tube. In the next step the red blood cells are irradiated by a laser that emanates a wavelength of about 633 nm for a time period of about 24 hours. During rotation the RBCs are rotated to provide uniform exposure. Such laser biostimulation produces an enhancement of shelf life of donor blood by 66%.

    Abstract: Methods and devices are provided for the extracorporeal ablation of target cells circulating in blood of an organism. Exogenous material introduced into the blood preferentially associates with target cells (e.g. cancer cells, bacteria, viruses) in the blood. An extracorporeal continuous flow pathway accesses the patient's blood to apply an external energy source to the blood at an ex vivo ablation device in a portion of the extracorporeal continuous flow pathway. The exogenous material interact with the applied energy so as to result in the damage or death of the target cells. The blood is then returned to the body in a continuous-flow pattern. By applying the energy while the blood is in the ex vivo ablation device, shielding of the target cells by the body is reduced and detrimental effects on the organs and tissues of the body are avoided or mitigated.

    Abstract: An extracorporeal fluid treatment apparatus includes a separator comprising a cartridge surrounding a porous separation membrane. The membrane separates a main flow path of a cellular component of the blood from a plasma flow path. An affinity medium is disposed within the plasma flow path to bind contaminants such as viral pathogens or toxins contained within the plasma. A pump pumps the plasma through the affinity medium at an assisted flow rate preferably between 10% and 40% of the whole blood flow rate. The assisted flow rate is selected to reduce a T90% of the apparatus by at least 50% as compared to a T90% of the apparatus without the plasma pump. A method of treating blood containing contaminants includes supplying infected blood to a separator and pumping the plasma component through an affinity medium at an assisted flow rate to increase contaminant clearance.

  • Patent number: 7867214
    Abstract: In a peritoneal dialysis embodiment of the present invention, spent dialysate from the patient's peritoneal cavity passes, along a patient loop, through a dialyzer having a membrane that separates waste components from the spent dialysate, wherein the patient loop returns fresh dialysate to the patient's peritoneal cavity. The waste components are carried away in a second regeneration loop to a regeneration unit or sorbent cartridge, which absorbs the waste components. The regeneration unit removes undesirable components in the dialysate that were removed from the patient loop by the dialyzer, for example, excess water (ultrafiltrate or UF), toxins and metabolic wastes. Desirable components can be added to the dialysate by the system, such as glucose and electrolytes. The additives assist in maintaining the proper osmotic gradients in the patient to perform dialysis and provide the necessary compounds to the patient.

  • Publication number: 20100331753
    Abstract: Methods for treating malaria are provided, the treatment comprising the step of removing malaria-infected red blood cells from the patient s blood. Blood is drawn from the patient s circulatory system and circulated through a blood purification device that selectively eliminates the infected red blood cells from all other blood s components and replaces the cleansed blood back into the patient s circulatory system. A blood purification device, which is useful to perform the therapeutic methods of the invention, is also provided. The device leverages the magnetic properties of the hemozoin contained within the infected red blood cells and comprises one or more separation chambers (4) though which blood flows through a high-gradient magnetic field generated by an array of wires (5) separated from the chambers and not in contact with the patient blood.

  • Publication number: 20100069814
    Abstract: A system and method of utilizing microbubbles and liposomes as viral sequestering agents. Microbubbles and liposomes having polyanions and conjugation systems are injected into the bloodstream of a subject human or animal. The microbubbles and/or liposomes attract virus particles including envelope viruses. After the microbubbles and/or liposomes have circulated in the blood for a pre-established time period, the microbubbles and/or liposomes along with attached virus particles are separated from the blood of the subject by passing the blood over or through a substrate or using a centrifuge. The substrate includes a conjugation system which has an affinity for the polyanions of the microbubbles and/or liposomes. As the microbubbles and/or liposomes and attached virus particles are removed from the blood, the viral titer of the subject is lowered.

  • Publication number: 20090292233
    Abstract: The Human Immunodeficiency Virus posses a significant threat to the world's population. Current strategies have not been adequate to contain and eradicate this deadly viral infection. HIV utilizes a T-Helper cell as a host to generate replicas of itself. Reversing HIV's own biologically deadly tactics and developing blood filtering techniques that incorporate filter mediums that engage the cell-surface receptors uniquely located on the surface of a T-Helper cell infected with the HIV genome can lead to terminating the infected T-Helper cells. Filter mediums possessing cell-surface receptors intended to terminate infected T-Helper cells by triggering apoptosis, is an effective means to eliminate HIV's host cells and thus provides a valuable strategy to prevent and treat AIDS. Similar techniques can be utilized to terminate other types of cells that act as hosts for pathogens as well as terminating cancer cells.

    Abstract: The Human Immunodeficiency Virus posses a significant threat to the world's population. Current strategies utilized to treat infectious agents have not been adequate to contain and eradicate this deadly viral infection. HIV seeks out its host, a T-Helper cell, by utilizing glycoprotein 120 probes to engage a CD4 cell-surface receptor located on the surface of a T-Helper cell. Developing blood filtering techniques that incorporate filter mediums that offer HIV virion's probes the opportunity to engage the cell-surface receptors they are seeking offers a means of neutralizing and removing HIV. Filtering the blood of a patient with filter mediums comprised of T-Helper cells, sheets of lipid bilayer or virus-like structures with each type of medium possessing cell-surface receptors intended to attract and engage HIV virions provides an effective strategy to prevent and treat AIDS.

  • Patent number: 7563240
    Abstract: A blood purification device has a blood purification element divided into two chambers by a semipermeable membrane, with a first chamber as part of a dialysis fluid loop and a second chamber as part of an extracorporeal blood loop. By virtue of an analysis unit operatively connected to a sensor in the dialysis fluid loop, the device provides simple and uncomplicated determination of the blood purification performance of the blood purification element for a second material by derivation from a previously established blood purification performance for a first material. In this way, the device also determines the blood concentration of the second material during the blood treatment through measurements in the dialysis fluid without intervention in the treatment sequence.

  • Publication number: 20090156976
    Abstract: Methods and devices are provided for the extracorporeal ablation of target cells circulating in blood of an organism. Exogenous material introduced into the blood preferentially associates with target cells (e.g. cancer cells, bacteria, viruses) in the blood. An extracorporeal continuous flow pathway accesses the patient's blood to apply an external energy source to the blood at an ex vivo ablation device in a portion of the extracorporeal continuous flow pathway. The exogenous material interact with the applied energy so as to result in the damage or death of the target cells. The blood is then returned to the body in a continuous-flow pattern. By applying the energy while the blood is in the ex vivo ablation device, shielding of the target cells by the body is reduced and detrimental effects on the organs and tissues of the body are avoided or mitigated.
